Years ago I came across filecoin/sia decentralized data storage and I started trying them but then I stopped due to lack of time. Some days ago I've heard in a podcast about a kind of NAS that does kinda the same thing: it spreads chunks of data across other devices owned by other users.

Is there a service that does this but with your own hardware or, even better, something open source where you can have X GB as far as you share the same amount of space plus something extra?

It would be great for backup.

When I go on vacation I prefer to keep my smartphone with WiFi and mobile data off, but I really don't like the way Spotify handle offline content. Most of the time it doesn't download everything and when I do a research, it show me even content that's not available offline (how can it do that?). Is there a selfhosted service that I can use to download my playlists and play them with an Android app that can download them?

I'd like to use my smartphone WiFi SSID to determine if I'm home or not. When I'm home the alarm (kinda, just notifications from some sensors) needs to be shut off and a light needs to be turned on. Since the sensors update can be forced at maximum 1 minute (but I'd prefer to leave it at 15 minutes to preserve battery) and since 1 minute is too much, is there a way to send an intent to HA companion app to send a sensors update? I would use Tasker to send the intent.

I've a VLAN dedicated to IoT devices and, of course, HA can't discover them. Is it possible have them discovered by HA via MQTT? Create them manually it's a pita because they're a lot and I would have to create sensors/switches + battery level + RSSI Thanks!

I've finally been connected to a fiber connection 2,5/1Gbps! 🥳 Now I want to share my connection with my neighbor and so I've installed 3 PCIx dual 1GB nic (I'm out of PCIe slots 🤷‍♂️).

The connections comes from my OPNsense to the server (Proxmox) via a 10Gbps fiber connection.

I want OPNsense to take car of firewalling dividing the neighbor networks with VLANs. The OPNsense part is done and working, I need to assign to each of the 6 1Gbps NIC each VLAN.

I've tagged the traffic going into the server via the fiber connection, but now how can I assign each VLAN to each NIC? Thanks!

Edit: Proxmox has nothing to do in the equation, it just happens to be on the same server where the NICs are.

I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can't find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I'd day 2 4K simultaneously) that is only PCIe 2.0 x4?

Edit: the x4 slot is full length.

Hi all! Do you know a valid app for GutHub? I've searched on F-Droid, but they are all abandoned. Thanks!

My Internet provider just installed a 2,5/1Gbps Internet connection and I've asked the guys to run a couple of their fiber to connect my router (HP Prodesk with OPNsense) to my server. I didn't know that the fiber is single mode and all the SFP+ sold used now seems to be all for multi mode fiber (www.bargainhardware.co.ukfor example). The cable is about 30m, can I use a 810nm SFP+ or is it definitely better to use a 1310nm?

Hi everybody! For my OPNsense router (on a VM on Proxmox) I need a 2,5Gbe card (to connect to the ONT of my provider); I only have 2 PCIe 3.0 x1 or 1 x4 because the only x16 is for a dual SFP+ fiber card.

Can you suggest me a NIC (I'd prefer to buy used)? Is it better to go with a 2,5 or 10Gbe? The cooler (temperature!) the better. I just need 1 port, if there are 2 it would be better, but the most important thing is the low operating temperature.

Thanks!

My Internet provider just installed me a 2,5Gbps fiber connection. It arrives with a single fiber connected to a GPON ONT (ZTE ZXHN F6005) connected with an RJ45 cable to the 2,5Gbps port of a 5530 Fritz!Box router. I'd like to bypass both the router and the ONT, do you think that it's possible? For the router my provider says that it's possible and it provided me the connection parameters, but for the ONT I've no idea. I would need a singe fiber SC/APC 2,5Gbps SFP+ adapter that I cant seem to find. Can anybody help me? 'm based in Europe.

I have installed Debian with software RAID1 (and installed Proxmox on it) on 2 256GB SSD and I now want to move to 2 500GB SSD, how do I proceed?

Edit: the RAID is of the OS disks.

Hi all, I have a Proxmox server hidden away where it annoys nobody, and a small PC I'm the TV cabinet that I need to turn On/OFF every time I use it and when a movie needs to be transcoded, the fan spins like crazy.

Have anybody tried to use a Windows VM and share the desktop with NDI? In this way I just need an NDI decoder behind the TV and all the job will be done by the server.

Any thoughts about this?

Edit: NDI: Network Device Interface: basically it's an audio/video (and intercom) transmission over IP with low latency. The sender could be an hardware encoder or a software.

I've found these NetApp SAS Festplatte 6TB 7,2k SAS 12G 3,5" - 111-02374 E-X4064A-R6 ST6000NM0034, that cost only 38€! It's a brand that I've never heard about and I've no idea how many hours they've worked (I've asked and I'm waiting for an answer). What do you think?

Edit: I've asked the seller if there is a custom firmware that makes the drive unusable and it answered me saying that they work with any SAS HBA controller. They have worked 1863h and written 130TB (he showed me 4 screenshots of 4 tests of 4 drives)

Hi all, I've bought 2 Dell H310 6gbps SAS HBA controlelr with cables, but the cables have the wrong connectors (for me). They have this:

While my drives have this one:

What's the name of those 2 so that I can sell mine and buy new ones? ...or should I just cut the side of these and power supply connectors? 🤔

Hi all, I don't know if this is the right place to post this...let me know :)

I'm trying to create a NFS share, this is my /etc/exports:

/mnt/pool/var_VM_docker/ 172.31.0.0/24(rw,sync,no_subtree_check)

When I try to connect with:

sudo mount -t nfs -o nfsvers=3 -vvvv 172.31.0.1:/mnt/pool/var_VM_docker /mnt/test

I get: mount.nfs: timeout set for Mon Apr 15 19:07:11 2024 mount.nfs: trying text-based options 'nfsvers=3,addr=172.31.0.1' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 172.31.0.1 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 172.31.0.1 prog 100005 vers 3 prot UDP port 41067 mount.nfs: mount(2): Permission denied mount.nfs: access denied by server while mounting 172.31.0.1:/mnt/pool/var_VM_docker

I don't have iptables enabled, nor SELinux. I've tried exporting it on 127.0.0.1 and connecting it to 127.0.0.1, but the problem persist. What am I doing wrong?

Fellow selfhoster, do you encrypt your drives where you put data to avoid privacy problems in case of theft? If yes, how? How much does that impact performances? I selfhost (amongst other services) NextCloud where I keep my pictures, medical staff, ...in short, private stuff and I know that it's pretty difficult that a thief would steal my server, buuut, you never know! 🤷🏻‍♂️

My home server is a Proxmox machine with some VM one of which is Open Media Vault from which a Windows PC plays videos to my TV. I want to get rid of the Windows PC and connect the TV directly to the server with an HDMI+USB RJ45 extender, but...how do I get a GUI from it? Is it even possible? I would need to connect to a Windows VM because for what I know Netflix only plays 4K videos with Edge. Thanks!

Hi all! I've been looking for a selfhosted system that can monitor one or more email accounts and check if a certain email with a particular subject arrives every day (or every x hours) and alert me if it doesn't (or if the subject is different). I need this to check if backups from different PC have run or not. The best thing would be to integrate it with Uptime Kuma. Any idea? Thanks!

Edit: I'm switching all my backup software to Restic (Autorestic on Linux machines) so I can send a ping to Uptime Kuma when every single backup successfully ends.

I've just discovered OmniGPT that seems to be a chat where you can interact with different LLM (Claude, GPT-4, Llama, Gemini, etc.) and costs $16/month (it was $7/month until a week ago 🤦‍♂️). I've read on a Reddit post that it uses the APIs of all the provider that is a thing that can be done for free using a personal account (since the API limit seems to be high). Do you know something like OminGPT that can be self hosted that uses users API keys?

Hi all! What do you think is the best chatbot to use for suggestion/learning vvvv, TouchDesigner and similar software? I will be using it also to check/suggestion on JavaScript/Python scripts. One where I can upload a file and let it analyze it would be very nice.
